Air/sludge separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air/sludge separators require frequent depressurization and water refill during cleaning, leading to inefficiencies and potential damage to heating systems due to magnetite buildup and contamination.
Innovation Solution
An air/sludge separator with an internal rotary slide that can shut off inlet and outlet openings, eliminating the need for external shut-off valves and minimizing water loss during cleaning, featuring elastic flat seals and a two-part housing design for easy disassembly and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external shut-off valves are installed before and after the air/sludge separator, then the separator can be isolated for cleaning, but the device complexity increases and requires additional components
Solution Approach 1:
The patent integrates the shut-off function directly into the separator housing by creating a removable lower section that can be detached to access and clean the magnetite separator. This eliminates the need for separate external shut-off valves by merging the isolation function into the housing structure itself, reducing component count while maintaining the ability to isolate and clean the separator.
2Ease of operation
If the sludge separator is opened for cleaning, then magnetite and sludge can be removed, but water must be drained and the system must be depressurized
Solution Approach 1:
The separator housing is divided into an upper stationary part and a lower removable part. The lower part containing the magnetite separator can be unscrewed and removed independently while the upper part remains in the system. This segmentation allows the cleaning operation to be performed on the removed lower section without requiring depressurization or draining of the entire heating system, significantly reducing cleaning time and operational disruption.
3Productivity
If the magnetite separator is cleaned by flushing, then sludge can be removed, but a corresponding amount of water must be drained resulting in water loss
Solution Approach 1:
By segmenting the housing into removable lower and upper parts, the patent enables the lower section to be detached and cleaned separately in a controlled environment. This allows for targeted cleaning of the magnetite separator using minimal water for rinsing the removed component, rather than requiring large-volume flushing operations that drain and lose significant amounts of heating water from the entire system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the depressurization process and reduces water loss during cleaning, allowing for effective and quick cleaning without the need for additional water refills, thereby protecting heating system components and maintaining thermal efficiency.
Implementation Method 1
in the shut-off position of the rotary valve sleeve (10), the inlet and outlet openings (3, 4) are sealed tightly
Implementation Method 2
The flat seals (12), which are formed from a plastic material which is more elastic than the plastic material of the separator housing (2)
Implementation Method 3
the upper part (5) or the upper end of the sleeve advantageously has an automatic air vent, which is connected to an inlet chamber leading from the inlet opening (3) and/or to an outlet chamber of the separator housing opening into the outlet opening (4)
Implementation Method 4
a magnetite separator with an integrated ball valve is known from the initially mentioned EP 3 332 855 A. This ball valve and two additional integrated non-return valves can be used to direct the volume flow through the filter area
